I've read that a ferret's liver has the ability to "regenerate".
What medications could do that?

One of my ADV positive boys, that I believe has Aleutian Disease, is
having very similar symptoms as my Cara Mia did. We put her to sleep
during exploratory surgery as liver failure was indicated. Sadly,
she has in such poor shape by then that I could not put her through
force feedings, etc. She was not eating and vomited the last meal
she ate.

My boy became very lethargic. I took him to the vet at 10:00 p.m. on
Tuesday evening as he also had hind leg weakness. He has vomited a
few times in the last few months. His fasting glucose was 83 and
fluid was found in his chest. He's been on Lasix and Amoxi since
then. His energy is better but he acts like his gravy tastes "bad".
He ate fairly well (after walking away a few times) this a.m., but
then vomited it up. He's also sleeping separate from his cage
mates...just like Cara Mia did.

Is there anything I can do to prevent him from becoming as ill as
Cara Mia? Can liver problems be treated? His GGT was 12 on a recent
blood test.
